However, at higher distortion levels the discrepancy becomes large. For instance, a signal with THD F 266% has a THD R of 94%. [4] A pure square wave with infinite harmonics has THD F of 48.3% [1] [14] [15] and THD R of 43.5%. [16] [17] Some use the term "distortion factor" as a synonym for THD R, [18] while others use it as a synonym for THD F ...

Spurious-free dynamic range (SFDR) is the strength ratio of the fundamental signal to the strongest spurious signal in the output.It is also defined as a measure used to specify analog-to-digital and digital-to-analog converters (ADCs and DACs, respectively) and radio receivers.
US Dollar Index and major financial events. The U.S. Dollar Index (USDX, DXY, DX, or, informally, the "Dixie") is an index (or measure) of the value of the United States dollar relative to a basket of foreign currencies, [1] often referred to as a basket of U.S. trade partners' currencies. [2]
Texas Instruments TI-84 Plus, the most successful graphing calculator in terms of sales. A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables.
An OHLC chart, with a moving average and Bollinger bands superimposed. An open-high-low-close chart (OHLC) is a type of chart typically used in technical analysis to illustrate movements in the price of a financial instrument over time. Each vertical line on the chart shows the price range (the highest and lowest prices) over one unit of time ...
The signal-to-noise and distortion ratio (SINAD) is a measure of the quality of a signal from a communications device, often defined as = + + +, where is the average power of the signal, noise and distortion components.
THD [3] uses a specially developed anoscope combined with a Doppler transducer to identify the hemorrhoidal arteries (originating from the superior rectal artery) 2–3 cm above the pectinate line. Once the superior rectal arteries are identified through the Doppler, a suture ligation is performed to effectively decrease the blood flow to the ...
